Plants named in 1837

A mandarin orange (Citrus reticulata), often simply called mandarin, is a small, rounded citrus tree fruit. Treated as a distinct species of orange, it is usually eaten plain or in fruit salads. The mandarin is small and oblate, unlike the roughly spherical sweet orange (which is a mandarin-pomelo hybrid). The taste is sweeter and stronger than the common orange. A ripe mandarin orange is firm to slightly soft, heavy for its size, and pebbly-skinned. The peel is thin and loose, with little white mesocarp, so they are usually easier to peel and to split into segments. Hybrids have these traits

Catharanthus roseus, commonly known as bright eyes, Cape periwinkle, graveyard plant, Madagascar periwinkle, old maid, pink periwinkle, rose periwinkle, is a perennial species of flowering plant in the family Apocynaceae. It is native and endemic to Madagascar, but is grown elsewhere as an ornamental and medicinal plant, and now has a pantropical distribution. It is a source of the drugs vincristine and vinblastine, used to treat cancer. It was formerly included in the genus Vinca as Vinca rosea. It has many vernacular names among which are arivotaombelona or rivotambelona, tonga, tongatse or

Delonix regia is a species of flowering plant in the bean family Fabaceae, subfamily Caesalpinioideae native to Madagascar. It is noted for its fern-like leaves and flamboyant display of orange-red flowers over summer. In many tropical parts of the world it is grown as an ornamental tree. It is a non-nodulating legume. Although its country of origin was unknown, it had been in widespread cultivation for centuries. Finally, in 1932, a natural colony was discovered on the west coast of Madagascar by J. Leandri.

Victoria or giant waterlily is a genus of aquatic herbs in the plant family Nymphaeaceae. The leaves are a remarkable size; Victoria boliviana produces leaves up to 3.2 metres (10 ft) in width. The genus name was given in honour of Queen Victoria of the United Kingdom.

Basellaceae is a family of flowering plants in the order Caryophyllales, in the clade core eudicots, according to the Angiosperm Phylogeny Group. The family comprises 19 known species of herbaceous plants in four genera: Anredera – 12 species Basella – 5 species Tournonia – 1 species Ullucus – 1 species All the species are climbing or trailing vines. Two species cultivated as food – Basella alba (Malabar spinach) and Ullucus tuberosus (ulluco) – have been bred to a more erect, compact form. Three species grow tubers – Anredera cordifolia and A. vesicaria produce them in the leaf axils or at

Catharanthus is a genus of flowering plants in the family Apocynaceae. Like the genus Vinca, they are known commonly as periwinkles. It is a perennial herb and a subshrub endemic to Madagascar, with the exception of Catharanthus pusillus (commonly known as the tiny periwinkle), which is found in India and Sri Lanka. The most widely known species is Catharanthus roseus due to its usage in traditional and modern medicine, specifically as a source of cancer-treating alkaloid chemicals.

Argyreia nervosa is a perennial climbing vine native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Though it can be invasive, it is often prized for its aesthetic and medicinal value. Common names include elephant creeper, woolly morning glory and Hawaiian baby woodrose. Its seeds are known for their powerful entheogenic properties, greater or similar to those of Ipomoea species, with users reporting significant psychedelic and spiritual experiences. The two botanical varieties are Argyreia nervosa var. nervosa described

Echinopsis is a genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. As of November 2025, Plants of the World Online used a broad circumscription of the genus, resulting in about 80 accepted species, ranging from large and treelike types to small globose cacti. The name derives from echinos hedgehog or sea urchin, and opsis appearance, a reference to these plants' dense coverings of spines. They are remarkable for the great size, length of tube, and beauty of their flowers, borne upon generally small and dumpy stems.

Cucurbita ficifolia is a species of squash, grown for its edible seeds, fruit, and greens. It has common names including black seed squash, chilacayote, cidra, fig-leaf gourd, and Malabar gourd. This species is grown widely from Argentina and Chile to Mexico. It is also cultivated in regions of the world including India, Japan, Korea, China, the Philippines, Ethiopia, Kenya, Tanzania, and Angola. No named agricultural cultivars have been recognized. Compared to other domesticated Cucurbita species, samples of C. ficifolia gathered throughout its range are relatively similar to one other in

Dioscorea polystachya or Chinese yam (shānyào, simplified Chinese: 山药; traditional Chinese: 山藥), also called cinnamon-vine, is a species of flowering plant in the yam family.

Miltonia, abbreviated Milt. in the horticultural trade, is an orchid genus comprising twelve epiphyte species and eight natural hybrids. The miltonias are exclusively inhabitants of Brazil, except for one species whose range extends from Brazil into the northeast of Argentina and the east of Paraguay. The genus of Miltonia was established by John Lindley in 1837, when he described its type species, Miltonia spectabilis. Formerly many more species were attributed to Miltonia, however, beginning in 1978, the miltonias from Central America and from cooler areas of northwest South America have

Kalanchoe delagoensis, formerly known as Bryophyllum delagoense and commonly called mother of millions or chandelier plant, is a succulent plant native to Madagascar. Like other members of Bryophyllum (now included in Kalanchoe), it is able to propagate vegetatively from plantlets that develop on its leaf margins.

Delonix is a genus of flowering plants in the family Fabaceae, subfamily Caesalpinioideae. It contains trees that are native to Madagascar and East Africa. By far the best known species is the Royal Poinciana (D. regia). The name of the genus is derived from the Greek words δηλος (delos), meaning "evident," and ονυξ (onyx), meaning "claw," referring to the petals. The common name, poinciana, comes from a former genus of the same name in which the members of the current genus Delonix were classified along with plants now placed in the genus Caesalpinia.
